T o all whom it may concern:

Be it known that I, IvAR vention being to provide a device of thischaracter which will hold the hair more firmly than combs heretofore in use.

In the accompanying drawings7 Figure 1 is a front view of the comb; Fig. 2 is a section on the line 2 2 of Fig. 1; Figs. 3 and 4 are sections on the lines 3 3 and 4 4 resp'ectively of Fig. 1; Figs. 5 and 6 are plan views of the two parts of the comb detached; Fig. 7 is a section on the line 7 7 of Fig. 1; Fig. 8 is a section on the line 8 8 of Fig. 1; Figs. 9 and 10 are views similar to Fig. 8, showing the two parts of the comb detached; Fig. 11 is a front view of a comb of modified form; Fig. 12 is a partial cross-section on the line 12 12 of Fig. 11; Fig. 13 is a transversev section of the form shown in Figs. 11 and 12 with parts broken away; Fig. 14 is a view similar to Fig. 13, showing details of further modified form; and Fig. 15 is an enlarged broken section of a further modified form of the comb.

Referring to the drawing, 1, 2, represent upper and lower plates, which are suitably curved, as is common with this class of combs, to conform to the shape of the head, and which carry integral therewith two series of teeth, 3, 4. Said plates 1, 2, slide upon each other, and may be secured together in various ways.

In Figs. 1 and 2, the plate 2 is shown as provided with recesses 5, and in said recesses slide loops', formed integral with the plate 1. lThrough said loops pass pins 7 which are driven downwards from the top of the plate 2, and thus serve to hold said plates together.

In the modification shown in Figs. 11', 12, and 13, the plate 1 is formed with slots 8 and through said slots pass stems 9 having heads 10 and screwed or otherwise secured to the other plate 2.

In the modification shown in Fig. 14, rivets 11 are used instead of bolts.

The stems 9 are slidably arranged in the slots 8 of the plate 1 and are rigid with the OSCAR LonsTRoM, a citizen of the United States, resid-v plateu 2, being screwed or otherwise fastened thereto so that the plates are held contiguous but relatively slidable.

In Fig. 14 a modification is shown in which the stems haveheads at both ends and constitute rivets, the heads engaging opposite sides of the contiguous plates. The arrangement of the stem is similar to the arrangement shown in the previous figure, the

construction being such that the plate 1 canA slide on the plate 2, the stems being slidably arranged within the slots 8.4

The teeth of the two series form pairs, one

tooth of the pair, attached to one plate, be-

ing preferably rounded or convex on the side next theother tooth of the pair, and said other tooth being correspondingly concave, the object being to provide a firm grip of the hair between theteeth. However, the adjacent sides of the teeth may be flat, and the teeth may be either straight or wavy. The teeth of one series are normally pressed against the teeth of the other series by means of springs 12, which may be of any desired form, but in the present instance are shown as coiled springs, lying in cylindrical pockets 13, formed half in each of the plates 1, 2,

`which are suitably stamped to vform such pockets.

A locking device,l which will retain the teeth of the two series apart from each other until the comb is placed in the hair, may or may not be used, as desired. Such locking device is shown in Fig. 3, in which a fiat spring 14 lies in a recess 15 in one of the plates and has one end secured thereto, the other end being formed into a hook 16 which engages ashoulder 17 formed in the inner side of the other plate, said hook 16 being released from said shoulder by pressing inwards a small button or stud 18, the inner end of which then presses against said flat spring and releasesthe locking device.

An important feature of this invention consists in the form of union of the teeth to the plates. sufficient strength in the teeth, and at the same time tol avoid undue thickness and clumsiness in the plates. To accomplish this result, in the first place each tooth is It is very necessary to Vretain made of a thickness nearly equal to the comvrespondingly beveled; S0 Ithat the bevels of f hereinafter.

the teeth extending from each of the plates the other plate. By this arrangement the cross-sectional area of the union of each tooth with its plate is the same as that of the tooth itself, so that, notwithstanding that the plate is made little more than half the thickness of the tooth, the strength of the union of the tooth to the plate is not on that account materially diminished.

In Fig. 15 is shown a modiiication of the comb in which two pairs only, of teeth are used. This formof the device has a cylindrical slideway 2O open at the ends and carrying near the ends, teeth 20L preferably formed integral with the slideway. Adjacent to the teeth 20a the slideway 20 has slots 24 for a purpose which will appear Cylindrical slides 21 are arranged movably within the slideway 20 and each has a rigid tooth 2liL extending therefrom and arranged in one of the slots 24 of the slideway. rlubular members 23 and 23a telescoping one within the other, are arranged within the cylindrical slides 21. A spring 22 is located within the member 23 and engages the closed ends of the slides 21, normally forcing them apart. The spring positions the slides so that the teeth 21a normally lie adjacent to the teeth 20a. By forcing the slides 21 inward against the tension of the spring 22 the teeth 21a are displaced and move within the slots 24 away from the respective teeth 20a. A band 25 embraces the pairs of teeth and is arranged in grooves 26 of the teeth. The band acts as a guide for the teeth.

The invention may be ornamented or otherwise fashioned to suit custom or individual taste. Moreover it is to be understood that any suitable material may be employed.

1. A retaining comb, comprising relatively slidable sections having teeth, theteeth of each section being separated a distance greater than the width of a tooth, a tooth of each of said sections being arranged between adjacent teeth of another of said sections means for normally holding said teeth together in pairs, means for locking said teeth in aV separated position, and means for releasing said locking means.

2. A retaining comb, comprising two relatively slidable sections having teeth, the teeth of each section being offset laterally into the plane of the teeth of the other of said sections, the teeth of each section further being separated a distance greater than the width of a tooth, said teeth being alternately arranged whereby the teeth move in alinement, while the sections move side by side.

3. A retaining comb, comprising two relatively slidable plates having teeth, the teeth of each of said plates being laterally offset to lie partly under the other of said plates, said teeth of each ol' said plates being separated a distance substantially in excess ot the width of a tooth, said teeth being alternately arranged, and means for resiliently holding said teeth together in pairs.

4. A retaining comb, comprising two eorrespondingly curved slidable plates having teeth, the teeth of each of said plates being of greater thickness than said plate and extending beneath the other of said plates, said teeth of each of said plates being separated a distance substantially in exc ol' the width of a tooth, said teeth being alternately arranged, and means for resilicntly holding said teeth together in pairs.

7. A retaining comb comprising two plates moving upon each other, each having a plurality of teeth, one of said plates having a series of loops, and the other plate having a series of recesses in which said loops slide, and pins secured in the latter plate and extending through saidlloops, substantially as described.

8. A retaining comb comprising two relatively slidable plates having teeth, the teeth of each of said plates being oll`set and being arranged between adjacent teeth of the other plate, one of said plates having a recess, the other of said plates having a loop arranged in said recess, and a pin passing through said loop and secured to said lirst plate.

9. A retaining comb comprising two relatively slidable plates having teeth, the teeth of each of said plates being otl`set and being arranged between adjacent teeth of the other plate, one of said plates having a recess, the other of said plates having a loop arranged in said recess, a pin passing through said loop and secured to said lirst plate, and a spring arranged between said plates and normally holding the same in position such that the teeth are held together in pairs.

10.
